Smoke test failure sends one message per python version

[delucchi-cmu]

e.g. https://github.com/astronomy-commons/hipscat-cloudtests/actions/runs/8015681836

The action failed for python 3.9 and 3.10, and was cancelled for 3.11. We received two alerts, but they each had the same action/run URL, so it looked like a totally duplicated message.

Would it be possible to have the notification step happen ... outside the python matrix scope? and send an alert if the run fails, not just for each job that fails?

This sounds similar to only creating one issue if a smoke test fails. See issue #433
